On a Semi-Related note, we had a Summoner in the campaign the other day. My skull kind of imploded from the sheer alarm of how powerful the Eidelon (or whatever it's called) was.

I will lend my support to skepticism regarding spellcaster HP, I think that was kind of a bad call rooted in Paizo trying to give everyone new toys. If I could change one thing, it'd be to move spellcaster HP down to its original. That just felt frivolous.
